The short answer is that an Operations Director runs operations as a function. A Chief Operating Officer runs the company’s day-to-day delivery as a member of the C-suite, with cross-functional authority across all operational functions and a board seat. At small UK SMEs the two titles are used almost interchangeably. At mid-market and larger firms they describe materially different roles, with materially different reporting lines, pay, and decision rights — and the choice has a habit of being made by accident rather than by design.
This guide is for UK CEOs, founders and chairs trying to decide whether their business needs an Operations Director, a COO, or — most often — a fractional version of one or the other. It draws on current 2025-26 UK market data and the patterns we see across the engagements Leadership Services runs into the mid-market.
The two roles in plain English
A useful working definition comes from EXEC Capital’s 2026 guide to hiring a COO: “An Operations Director manages a defined operational function — typically manufacturing, service delivery, or supply chain — reporting to the COO or CEO. A COO is a C-suite executive with cross-functional authority across all operational functions of the business, reporting to the CEO and sitting on the executive board” (EXEC Capital COO recruitment guide).
In practice, the differences land in four places:
- Scope. The Operations Director owns one slice of operations end-to-end. The COO owns all of operations, plus the integration between operations and the rest of the business.
- Authority. The Operations Director acts within their function and within the budget allocated to it. The COO has cross-functional authority — they can call decisions between functions that an Operations Director cannot.
- Board status. The Operations Director rarely sits on the main board. The COO is a C-suite executive and usually a board member, often the deputy to the CEO.
- External-facing weight. The COO regularly fronts investors, lenders, large customers and the board. The Operations Director is more often internally focused.
A fifth difference is often invisible until something breaks: a COO is expected to absorb operational ambiguity and resolve cross-functional issues that no functional director can solve at their own level. That brokerage role is what makes the C-suite designation real, not honorary.
How the role looks at different company sizes
In a UK SME below roughly £15m turnover, “Operations Director” and “COO” are often the same person with a different business card. The role is broad, hands-on, and reports to the CEO or founder. Titling is driven more by external perception (investor decks, customer pitches) than by underlying structure.
From £15m turnover and a workforce of 50+, the roles start to diverge. The COO typically becomes the operational counterpart to a more strategically-focused CEO, runs a senior management team, and carries explicit responsibility for the operational KPI framework. The Operations Director, where the role exists separately, runs a defined operational function — production, supply chain, customer operations, service delivery — and reports to the COO or directly to the CEO.
By the time a business approaches £100m and a few hundred people, the two roles are unmistakeably distinct. The COO sits on the executive committee and the board. Multiple Operations Directors typically report to them, each running a function or business unit.
Svastlexis’s 2025 operations director guide captures this neatly: in larger structures the Operations Director “translates strategic intent into measurable results, while the COO or MD provides overarching governance and external-facing leadership” (Svastlexis Operations Director guide).
Salary and total cost in 2026
The UK market for both roles tells you a great deal about how the seniority gap is real:
- Operations Director (UK mid-market, 2026): Base salary typically £68,000–£128,000, with experienced operators above 75th percentile reaching £175,000+ (Glassdoor UK Director of Operations salary data).
- COO (UK mid-market, 50–250 employees, 2026): Base salary £95,000–£150,000, with total compensation including bonus £120,000–£200,000 (Data Driven Daily COO Salary UK 2026).
- COO (FTSE 250 and larger): Typically 50-70% higher than an Operations Director in the same organisation.
Add roughly 25-35% on-cost — employer National Insurance at 15% from April 2025, pension auto-enrolment, benefits and recruitment fees — and a permanent COO at a mid-market business is realistically a £200,000+ all-in commitment in the first year. An Operations Director runs closer to £120,000–£170,000 all-in.
For UK SMEs below £15m turnover, both numbers usually outrun the available executive budget, which is why the fractional model has become the dominant pattern in this segment.
When you need an Operations Director (not a COO)
You probably need an Operations Director if most of the following are true:
- The CEO or founder is still close enough to the business to run operational integration personally
- The operational complexity is concentrated in one function (manufacturing, logistics, customer operations) rather than spread across many
- The business has fewer than 100 people and one or two main operational pillars
- You have functional heads who are competent in their own areas but lack the seniority to translate strategy into execution
- The current bottleneck is delivery against the plan, not the plan itself
In this profile, an Operations Director gives you exactly what is missing: a senior operator who turns strategy into operational reality and runs the team that delivers it. A full-blown COO appointment would be premature.
When you need a COO
A COO becomes the right answer when:
- The CEO needs to spend their time externally — fundraising, M&A, key customers, public profile — and someone has to run the business while they are doing it
- Operational complexity has outgrown what any single functional director can resolve at their own level
- The executive team needs a clear deputy to the CEO who can chair the senior management team and act for the CEO when required
- The business is going through a major operational transformation — post-acquisition integration, ERP replacement, scaling from £15m to £50m, regulatory remediation
- The board wants a credible operational counterpart to the CEO, especially in private equity-backed businesses with explicit operational improvement plans
- The CEO is preparing for succession and wants to test a successor in a deputy role before any handover
EXEC Capital identifies four patterns of COO in the UK mid-market — operational delivery leader, second-in-command, transformation leader, and functional executive (EXEC Capital, How to Hire a COO). Most UK mid-market businesses appointing a COO for the first time fall into one of the first two patterns.
The fractional question — and why it usually wins
For UK SMEs in the £1m–£25m revenue band, a full-time COO rarely makes economic sense. The role would be 60–70% under-utilised, and the cost crowds out other senior hires the business needs more urgently. Simon Wakeman, a UK fractional COO, frames the threshold cleanly: a full-time COO typically makes sense once the business has 50+ people, consistent revenue to support a £150,000–£250,000+ all-in salary, and enough operational complexity to keep a senior executive busy five days a week (Simon Wakeman, What is a fractional COO).
The fractional COO model gives a mid-market business:
- 2–4 days per week of board-grade operational leadership
- A monthly fee typically £6,000–£15,000 plus VAT
- A 6–24 month engagement window aligned to a defined operational programme
- No long-term tie-in, no equity dilution, no recruitment fees
- Pattern recognition from operators who have been through the same scale transitions multiple times
In our experience this is the right answer for 80%+ of UK SMEs that think they need a permanent COO. The exceptions are businesses where the role is genuinely full-time from day one — typically PE-backed mid-market businesses with explicit operational value-creation plans.
Operations Director vs COO vs MD — clearing up the last bit of confusion
The picture is muddier still when Managing Director enters the mix. The cleanest distinction:
- Operations Director owns operational execution within a defined function or operational scope. Reports up.
- COO owns operational delivery across the business as a C-suite executive. Reports to the CEO.
- Managing Director owns the P&L of the business or a divisional business unit, including the commercial outcomes. In group structures, MDs of subsidiaries often report to a Group CEO while a Group COO manages operational performance across the portfolio.
A practical test: if the role you are scoping has P&L accountability for the entire business or a division, you are looking at an MD or a CEO, not a COO. If it has cross-functional executive authority but the CEO retains the P&L, you are looking at a COO. If it owns a single operational function and reports up, you are looking at an Operations Director.
How to choose for your business — five diagnostic questions
If your board is genuinely torn between Operations Director and COO, these five questions usually resolve it:
- Where is the CEO spending their time today? If the CEO is forced to run internal operational integration personally, the business needs a COO to free them up. If the CEO is comfortable running operational integration and what is missing is functional delivery, an Operations Director.
- What is the cross-functional load? If most operational issues sit cleanly inside one function, an Operations Director. If they spill across operations, technology, finance and people repeatedly, a COO.
- What does the next 24 months look like? A multi-year transformation, an acquisition integration or a scale-up from £15m to £50m almost always calls for a COO. Steady-state operational improvement points to an Operations Director.
- Who else is on the executive team? A business with a strong CEO, CFO and CCO but no operational counterweight at executive level usually needs a COO. A business with senior functional heads but no senior operations leader needs an Operations Director first.
- What can the business afford full-time? Below roughly £15m turnover, neither role is usually viable full-time. The fractional model is almost always the right starting point.

Frequently asked questions
Q: What is the difference between an Operations Director and a COO?
A: An Operations Director runs operations as a function, typically owning one operational pillar such as manufacturing, supply chain or customer operations, and reports to the COO or CEO. A COO is a C-suite executive with cross-functional authority across all operational functions, reports to the CEO, sits on the board, and is usually the operational deputy to the CEO.
Q: Do you need a COO and an Operations Director in the same business?
A: At mid-market and larger UK businesses, yes — the COO sets the operational framework and runs the senior management team, while one or more Operations Directors run specific functions. At UK SMEs below roughly £15m turnover, one role usually covers both, with the title chosen for external perception.
Q: How much does a COO earn in the UK in 2026?
A: Mid-market UK COOs (50–250 employees) typically earn a base salary of £95,000–£150,000 with total compensation £120,000–£200,000 including bonus. Larger corporate and FTSE 250 COOs earn 50–70% more than an Operations Director in the same organisation. A fractional COO engagement typically costs £6,000–£15,000 per month for 2–4 days a week.
Q: When should an SME hire its first COO?
A: Most UK SMEs are ready for a fractional COO well before they are ready for a full-time one. Triggers include: the CEO needing to spend significant time externally, operational complexity outgrowing functional directors, a major transformation programme, post-acquisition integration, or a CEO preparing for succession. Full-time normally makes sense at 50+ people and £15m+ turnover.
Q: Is a Managing Director the same as a COO?
A: No. An MD typically carries P&L accountability for the business or a division — they are accountable for commercial outcomes. A COO is accountable specifically for operational delivery — cross-functional execution, process management, cost efficiency — while the CEO or MD retains the P&L and primary external relationships.
